How to reconfigure the gpio to spi?

[danielchai]

Hi all,

I am try to use a set of I/O pins fordifferent purpose in different function.

FIrst I configure them as normal gpio. Then how can I configure them to SPI function  using MQX function?

Can I just directly use fopen to open SPI or I need to release the gpio, then reconfigure them as SPI?

Thank you.

Daniel
